microblaze has only two-level page tables and can use pgtable-nopmd and
folding of the upper layers.

Replace usage of include/asm-generic/4level-fixup.h and explicit definition
of __PAGETABLE_PMD_FOLDED in microblaze with
include/asm-generic/pgtable-nopmd.h and adjust page table manipulation
macros and functions accordingly.

I have take a look at this and when this is applied on the top of
5.4-rc2 there is not a problem.
But as was reported by 0-day there is compilation issue on the top of
mmotm/master tree and I am able to replicate it.
It means there are other changes in Andrew's tree which are causing it.

Thanks,
Michal
